36 Weeks, feeling so exhausted and weak all the time

Everything hurts. I can’t stand for longer than 5 min. My arms feel so weak I am legitimately struggling to hold my phone up. I cannot sit at my computer to play Sims which just feels cruel. My hips hurt like hell. I just want to lie down and not move. And I can’t, I have to work for 2 and a half more stupid weeks. My terror over the actual birth has been completely overshadowed by my desire for this to be over.
